I haven't tried this yet, but will next summer:

Also coconut oil masks the body. As long as you haven’t sweated your smell through your close a light oil topping may buy you several hours of concealment.

I'd install a device if there existed one: say something 2 meters high from the ground that can throw lasers but only on the vertical part of the wall (so above human eye level). A high res camera. Detect mosquito: fire laser.

These little fuckers shall, invariably, fly and land on the upper part of the various walls.

Maybe just a wide (say 2 feet / 60 cm) dual-sided tape: I'd tape happily that to the upper part of the walls in my room. Mosquitoes are bound to land there.

I agree it's insane we're in 2025 and this hasn't been solved yet. The company to solve the mosquito issue is going to be richer than NVidia.

Just invent these things: I'll buy them all. Just as I bought several of these anti-mosquito electric rackets and they're honestly a godsend compared to the "roll a magazine and try to squish the mosquito" from my youth.

door discipline, dont keep it open, sweep yourself for piggybackers.

electric mosquito racket.

We have genetically engineered mosquitoes that breed with wild types that reduce the life span of adult mosquitoes to reduce the spread of disease. We have biological agents that do the same. We have chemicals that stop the larva from developing into adult mosquitos. We have chemicals that can be vaporised to deter mosquitoes. We also have chemicals that you can apply that will stop mosquitoes from biting you (and will melt plastic).

Or just use a fly screen. I built one recently for my awning style window.

Look up thermacell devices and methoprene pelletes

It is not a repellent but seems to actively kill them/render them unable to fly [Metofluthrin (Pyrethroid)]

Fun fact for Twin Cities residents, the Metropolitan Mosquito Control District covers the same counties as the Metropolitan Council but was formed over a decade earlier!

When I have to leave comfort of this area and deal with nature, I use DEET spray.
